As part of the essential refurbishment and strengthening of this iconic London flyover, roller bearings at the base of the supporting piers were replaced due to wear, corrosion and the ever increasing vehicular traffic volume. The replacement spherical sliding bearings are located in underground bearing pits, which are now covered by an encapsulating row of bespoke FRP GRP trench covers. The cover design layout accommodates minor movement of the pier.
The previously installed concrete recess covers were cumbersome, preventing easy inspection and maintenance access to the bearing pits. They also exhibited major fatigue. A solution was required in specific sizes with a securing mechanism to prevent unauthorized unauthorised removal of the covers while allowing easy access when essential maintenance was required. As the covers would potentially experience both pedestrian foot traffic and the occasional vehicular wheel the covers had to be designed for both environments.
Fibrelite worked in close collaboration with the designing engineers (Ramboll) and the installation contractor (Pro Steel) to design, manufacture and deliver a custom made covering solution for the 15 piers, totaling totalling 500 individual FRP GRP trench covers encapsulated within a purpose designed frame. The bespoke FRP GRP trench covers were equipped with locking device to prevent unauthorized unauthorised access.
Handling pedestrian and vehicle traffic was achieved by supplying a C250 (25 ton) tonne) load rated cover with a unique anti-slip/skid tread pattern surface.
Fibrelite’s FRP GRP composite access covers have an inherent resistance to corrosion, offering a maintenance free ‘fit-and-forget’ solution. This means when you fit Fibrelites, they will continue to perform over time and retain their snug fit, minimizing minimising water ingress. When essential maintenance is required, the lightweight trench covers can quickly, safely and easily be removed using the custom ‘key’ and Fibrelite’s ergonomically designed lifting handles. Independent wet and dry tests carried out by Devon CC Materials Laboratory showed that Fibrelite manhole and trench covers – even when wet – have anti-slip/skid properties far exceeding health and safety advisory limits. All Fibrelite access covers are BS EN 124 load test compliant, meaning consistent high quality is assured.
